V6 3.6 FSI and V8 4.2 FSI
All Audi Q7 petrol engines feature FSI ® direct-injection – a unique Audi technology originally
developed for the Le Mans 24-hour endurance race to deliver increased power and torque as
well as enhanced fuel efficiency. The way it does this is, in theory, very simple. Precisely the
right amount of fuel and air are injected directly into the combustion chambers, enabling the
engine to ‘breathe’ more easily. At the same time, electronics monitor the engine load and
adjust the injection process. The result – reduced heat-loss and increased output, with around
a 15% reduction in fuel consumption and significantly lower exhaust emissions. Ideal for the
buyer who wants a sporty, exhilarating drive without the drawbacks of excessive fuel costs or
higher emissions.
V6 3.0 TDI and V8 4.2 TDI
All diesel engines from Audi are known as TDI. This impressive technology was originally
pioneered by Audi in 1989, marking a departure from the noisy, fuel-thirsty diesel engines of the
past. Like its FSI petrol counterpart, the TDI diesel engine is designed for power and performance,
with low fuel consumption and CO
2
emissions. All Audi Q7 TDI engines are based on the common
rail system. Here, fuel is stored and kept at constant pressures of up to 600 bar, ready to feed a
series of highly-accurate piezo injectors, which control the rate and point of injection.
